A high incidence of leukocyte chimerism (60,XX/60,XY) in single born heifers culled due to underdevelopment of internal reproductive tracts

open access: yesCzech Journal of Animal Science, 2014
Freemartinism, a primary disorder of sex development (DSD) in cattle, is associated with leukocyte chimerism (60,XX/60,XY). The diagnosis of DSD is easy if it is known that a heifer with abnormally developed reproductive tracts originates from a ...

Multiple congenital malformation in a Simental female calf: a case report

open access: yesVeterinární Medicína, 2010
Congenital anomalies in offspring of natural breedings are often a result of environmental factors, genetic factors, or both. A 21-day-old male Simental female calf was submitted to our clinic with abnormal severe green mucoid nasal discharge from both ...

Chromosome fragility in Freemartin cattle

open access: yesItalian Journal of Animal Science, 2007
The aim of the present study was to verify chromosome fragility in freemartin cattle using chromosome aberration (CA) and sister chromatid exchange (SCE) tests. A total of eighteen co-twins were investigated. Fourteen animals were identified as cytogenetically chimeric (2n=60, XX/XY) while 4 were classified as normal.

Randomised clinical trial evaluating the effect of different timing and number of fixed timed artificial inseminations, following a seven‐day progesterone‐based protocol, on pregnancy outcomes in UK dairy heifers

open access: yesVeterinary Record, Volume 181, Issue 22, Page 595-599, December 2017., 2017
The objective of this study was to determine the effect on pregnancy outcome of either inseminating heifers twice (at 48 and 72 hours after withdrawal of a controlled internal drug release insert (CIDR) containing progesterone) or once (56 hours after CIDR withdrawal) following a seven‐day CIDR synchronisation protocol.

Combined Bone Marrow and Kidney Transplantation for the Induction of Specific Tolerance

open access: yesAdvances in Hematology, Volume 2016, Issue 1, 2016., 2016
The induction of specific tolerance, in order to avoid the detrimental effects of lifelong systemic immunosuppressive therapy after organ transplantation, has been considered the “Holy Grail” of transplantation. Experimentally, tolerance has been achieved through clonal deletion, through costimulatory blockade, through the induction or infusion of ...

Development and External Validation of a Predictive Model of Severe Neonatal Calf Diarrhea in Hanwoo Calves Using Animal, Environmental, and Management Risk Factors

open access: yesJournal of Veterinary Internal Medicine, Volume 39, Issue 5, September/October 2025.
ABSTRACT Background Neonatal calf diarrhea accounts for most pre‐weaned calf losses in Hanwoo cattle. A novel predictive model of severe neonatal calf diarrhea will help veterinarians and farmers prevent disease in calves. Hypothesis/Objectives Development and external validation of a simple predictive model for severe neonatal calf diarrhea in Hanwoo ...

Chimerism‐Based Experimental Models for Tolerance Induction in Vascularized Composite Allografts: Cleveland Clinic Research Experience

open access: yesJournal of Immunology Research, Volume 2013, Issue 1, 2013., 2013
The preclinical experimental models of vascularized composite allografts (VCAs) have been rapidly developed for the assessment of immunomodulatory protocols for clinical application. Recently, researchers have focused on immunomodulatory protocols which overcome the immunologic barrier between the allogeneic donor and recipient and may lead to ...
